The high and low temperature impact box has simple and convenient operation performance and reliable equipment performance, and is used in many fields, such as aviation, aerospace, electronic components and materials research. But try not to open the door of the test chamber when operating the equipment. If you must open it, please do some protection work.
1. The structural characteristics of the high and low temperature impact box
1. The product has beautiful appearance, reasonable structure, advanced technology, exquisite material selection, simple and convenient operation performance and reliable equipment performance. The equipment is divided into three parts: high temperature box, low temperature box and test box. Adopting a unique thermal insulation structure and thermal storage effect, the test object is completely static during the test, and the cold and hot air path switching method is used to introduce the cold and hot temperatures into the test area to achieve the purpose of cold and heat shock testing.
2. The most advanced measuring device is adopted, and the controller adopts a large color LCD man-machine touch dialogue LCD man-machine interface controller. Simple operation, stable and reliable, complete system operation status, execution and setting program curve displayed in Chinese and English. With 96 test specifications independently set, the impact time is 999 hours and 59 minutes, and the cycle period can be set from 1 to 999 times. It can realize the automatic operation of the refrigerator, and realize the automation to the greatest extent, reduce the workload of the operator, and can be automatic at any time Start and stop work operation.
3. There is a test hole with a diameter of 50mm on the left side of the box, which can be used for external power load wiring test components. Three different conditions of high temperature, low temperature and thermal shock can be set independently. And when performing cold and hot shock conditions, you can choose two-slot or three-slot type, cold punching, hot punching for impact, and it has the function of high and low temperature testing machine.
4. Equipped with fully automatic, high-precision system loop, any machine action, PLC lock processing, all adopt PID automatic calculation control, high temperature control accuracy. Advanced scientific air circulation design, make the indoor temperature uniform, avoid any Dead corners; complete safety protection devices avoid any potential safety hazards and ensure the long-term reliability of the equipment.
5. The number of cycles and the number of defrosts can be set to automatically (manually) defrost. The air outlet is detected and controlled by the return air outlet sensor, and the switching time of the damper mechanism is completed within 10 seconds. The temperature recovery time of Lishan brand hot and cold shock is within 5 minutes. State display and curve display during operation. When an abnormal situation occurs, the screen will automatically display the point of failure and the reason and provide a method of troubleshooting. At the same time, when the input power is found to be unstable, it has an emergency shutdown device.
6. The refrigeration system adopts the design of a cascade high-efficiency low-temperature circuit system, and the refrigeration unit adopts imported compressors from Europe and the United States, and adopts the green environmental protection (HFC) refrigerant R507, R23 with zero ozone coefficient. Super safety protection function: power supply overload protection , Leakage protection, control circuit overload, short-circuit protection, compressor protection, grounding protection, over-temperature protection, alarm sound prompts, etc. UV Carbon Arc weather MeterUV Aging Test ChamberOzone test chamber
